Lipitor, also known as atorvastatin, is a medication primarily used to lower cholesterol levels and reduce the risk of heart-related conditions. While increased hunger is not commonly listed as a side effect of Lipitor according to sources like Drug Patent Watch [1], Healthline [2], and the Mayo Clinic [3], it is important to note that individual responses to medications can vary. It is always recommended to consult with a healthcare provider if you experience any unusual symptoms or changes while taking Lipitor.
